IMPROVEMENT IN -CIULTIVATORS.

Specification forming part of Letters Patent No. 171,420, dated December2l, 11.375; application tiled November 6, 1875.

To all whom it may concern:

Be it known that I, J osEUA PIERPONT, of Bushnell, county of McDonoughand State of Illinois, have invented certain Improvements inGultivators; and I do hereby declare that the following is a full,clear, and exact descriptionV thereof, which will enable others skilledin the art to which it pertains to make and use the same, referencebeing had to the accompanying'drawing and to the letters of ret'- erencemarked thereon, which form a part of this specification.

My invention relates to improvements in braces for the standards ofcultivator-plows; and the invention consists, irst, in constructing themetallic block through which the brace passes witha Vertical series ofholes for the connecting-pin, by means of which small degrees ofadjustment may be effected, and, second, in improvements in the mannerof securing said blocks to the standards, all as hereinafter fullydescribed.

Figure l in the drawings is a side elevation of a cultivator-plowembodying my invention. Fig. 2 is a perspective view ot'one oftheblocks, alone. Fig. 3 is a vertical sectional view through the block,and a side elevation of portions of a plow, enlarged.

Referring to the drawing by letters, letter A represents the beam, B Bthe standards, G C the shovels, and D the handles, of an ordinarycultivator-plow. E is the standard-brace, its upper end secured by abolt to the side of the beam A, and its lower end perforated with aseries of holes, c. Gr is a metallic block, slotted from front to rearfor the passage of the brace E, its front side adapted to tit againstthe rear side of the standard B, and its rear side having projectinglugs g, which it will be evident from the dotted-lineillustral tions atFig. 3 that, by using the break-pin in the same hole in the brace E anddi'erent holes of the series in the lugs g, very slight degrees ofadjustment of the standards may Y be effected, and by also using thedifferent series of holes c in the brace, other and greater degrees ofadjustment may be eected.

Having thus described my invention, what I claim. as new, and desire tosecure by Letters Patent, is

l. The block G, constructed, as described,

with lugs g, series of holes g', and prongs h, substantially as and forthe purpose specied.

2. The block Gr, having prongs It and lugs g, with a series of holes,g', combined for operation with the brace E, pin o, standards B,

and plow-beams A, substantially as and forV the purpose specified.

In testimony that I claim the foregoing as my invention have hereuntoaflixed my signature.

JOSHUA PIEEPONT.
